Abstract :
A method for deriving the location of houses and roads from scanned NHAP and NAPP aerial photography using spectral, spatial (spatial smoothing and filtering and road segment size), and contextual (proximity to road) techniques was demonstrated. Despite differences in house size and construction age, analysis of both test and verification sites achieved acceptable accuracies, with more than 92 percent of the houses correctly identified. This house and road image derived from scanned USGS NHAP aerial photography, demographic data from the Bureau of the Census TIGER/Line files, and digital terrain data provided by the USGS Digital Elevation Model (DEM) files were then combined using analysis techniques developed to utilize imagery from spaceborne multispectral instruments
